Increased capacity disc dryer

Abstract

An improved disc dryer for aggregate material which operates by rotating and impacting a tilted pan which holds the material being dried. Increased capacity is attained by transverse stabilizers on the impactor assembly, adjustable pressure air shock mounts for variable amplitude control of the impactor assembly, sets of dual support wheels upon which the pan rotates a reinforced support tract on the underside of the pan, and an adjustable feed box for supplying material to the pan at varying locations.

What is claimed as new and for which Letters Patent of the United States are desired to be secured is: 
     
       1. In a dryer for aggregate materials of the type comprising a pan with retainer sides, the pan being oriented at an angle to the horizontal, being rotated upon wheels by which it is supported and being impacted by an impactor assembly to induce vibration, the improvement comprising: at least one transverse stabilizer constructed of a vibration isolating member attached to a portion of a fixed structure from which the impactor assembly is supported and also attached to a portion of the impactor assembly, with the transverse stabilizer oriented so that is primarily resists horizontal forces applied to the impactor assembly by the compression of a compression member of the transverse stabilizer, and does not significantly resist vertical motion.   
     
     
       2. The dryer of claim 1 wherein a transverse stabilizer is constructed with a casing within which the motion of an enclosed piston is resisted only by a rubber piece which is held in place by the casing and an end fitting located on the opposite side of the rubber piece from the piston. 
     
     
       3. The dryer of claim 2 wherein the end fitting of the transverse stabilizer is adjustable in its location in order to adjust the resistance of the transverse stabilizer.
